Purpose. Substantiating technological parameters of the device for processing vuggy zone in the bore hole, based on the obtained dependences describing formation and withdrawal of clay-mud agglomerates and their influence on the results of plugging bore holes. Methods.As a result of carrying out laboratory and theoretical researches, principles governing formation of claymud agglomerates and their influence on the technological indexes of building bore holes have been determined. Findings.Reasons for the phenomenon of bore hole plugging are analyzed. It is shown that boring works efficiency is directly related to the quality of carrying out operations on bore hole casing. Influence of agglomerate slope angle and coefficient of rugosity on the volume of clay-mud pastes in the complicated intervals has been studied. Impact of the clay phase on the strength indexes of plugging stone has been analyzed. Validity of the obtained data has been confirmed by methods of mathematical statistics. The mechanism defining the impact of active drilling liquid streams on the vugular sludge agglomerate has been investigated. Further areas of research into perfecting the technology of bore holes' casing have been identified.Originality. The quality of works on casing and plugging implementing the device for processing the bore hole is determined by the reduction of the sludge agglomerate slope angle in proportion to vugg thickness.

To substantiate the design and operating technological parameters of the device for the interval bore hole cleaning departing from the set dependences of active jets formation in the flow through the blade element.Methods. Application of bench and analytical research techniques allowed to establish the fundamental principles of active jets formation in the flow through the blade element of the designed device and the nature of their impact on the processed objects.Findings. Bench testing of the device for the interval bore hole cleaning resulted in defining aspects of the mechanism of active fluid jets formation. We studied the distribution of speed components in the workflow. The use of tilted surface for the formation of the blade profile has been justified.

The indicators of the effectiveness of the designed device were designated.Originality. The steady flow through the blade element and consequently the removal of clay-mud agglomerates is provided by well-defined structural design characteristics which determine hydrodynamic aspects of the unit operation. Practical implications.The results of laboratory and analytical studies are the base for designing the operating parameters of the process of preparing a bore hole for casing running and subsequent plugging of the bore hole with a guaranteed provision of high technical and economic indicators. Data for the study of the flow mode through the blade element are the basis for the hydrodynamic calculation of the device for the interval cleaning.
